Application April 12, 1954, SerialNo. 422,319- 4 Claims. (Cl. 33-197) The presentiinvention relates to ameans for locating and forming recesses for hinge plates.

. States Patentf) Heretofore, therefhas been a problem in the building trade of properly and quickly locating hinge plates on doors and door frames. Efforts have been made to overcomet-his problembut'thes'e have resulted incomplicated attachments which, for the most part", could be used only on the door and could not be attached to the frame to cooperate toproduce the necessary recesses therein.

The present invention overcomes these difficulties by providing anovel attachment which can be used to guide a r u'ting tool incuttingtherecess for-the hinge plate on the doororframe-and onewhich can be readily and easily installed; The present invention also provides a novel means for locating these attachments to greatly facilitate the op'cration of hanging a door.-

The novel" attachment for carrying out the presentinve'ri'tiori is adapted to be temporarily secured to the sur face of' the door or frame to be routed and includes a base member-having a detachable template means thereoirfor guiding the routing-tool. The template-plates with guide openings formed therein, according to the type of hinge that is to be mounted, can be readily mounted on the b'a se and are provided with a locating flange means which assists in locating the template-plateon the base and also in locating the attachment in position on the surface which is to be routed.

In accordance with the present invention a simple, novel gaugemenrber is provided by which a novel method; for Quickly: and accurately locating the required number of attachmentsto be secured to the door and/or frame can be carried out. U

Other features and advantages of the invention; will he apparent fromthe specificationand claims when considered! in connection" with the drawings in which Figure 1 shows a top plan view of the attachment.

Fig. 2 is a side view.

Fig. 3 shows a view of the attachment being secured in position to a door.

Fig. 4 is a view of the gauge.

Fig. 5 is a detail of the top view of the gauge member.

Fig. 6 shows the relation of the gauge member to the edge of the door.

Fig. 7 shows the relation of the gauge member to the. door frame.

Fig. 8 is a sectional view showing the attachment in position on a door.

Fig. 9 is a sectional view showing the attachment in position on the door frame.

As shown in the drawings, the attachment comprises a base 10 which is in the form of a base plate 11 of any suitable material which is adapted to overlie the surface to be routed. The base plate is provided with apertures 12 adjacent the ends thereof through which a fastening means, such as a nail 13 or the like, may be driven to temporarily secure the attachment in position. The attachment has a recess 14 extending inwardly from one side intermediate the ends. A template-plate 15 which 2,789,359 a en e rt 1.9

2 is preferably formed of'sheet metal is detachably secured to the top surface of the base by means of screws 16. As shown in Figs. 1 and 2, the template has a flat top 17 which is provided with recess 18 adapted to be positioned over recess 14 in the base plate with the edges of the recess forming tool guiding surfaces 19 shaped to conform to the particular hinge plate being set. The template is provided with locating flange means 20 which are bent from the plate, preferably perpendicularly to the top 17 of the template so as to extend down over the side of the base plate and below the base plate to engage a side surface of the support to which the attachment is secured, as shown in Figs. 8 and 9, to locate the attachment thereon in a predetermined positionwith respect to the edge of a support. The template is also provided with guiding members 21 adjacent each side of the recess 18 and have a surface 18aforming, in effect, a continuation thereof projecting laterally from the template beyond the locating flanges which serve to guide the routing tool into the opening. It will be noted that the fiat top 17 of the template provides a supporting surface of the router and provides for smooth operation thereof during the routing operation and an accurate control of the depth of the cut.

A feature of the present invention resides in the fact that the attachment can be secured to the edge of a door 22, as shown in Fig. 8 or to the edge of the door frame 23-, as shown in Fig. 9 to permit routing of either surface for the hingeplate. As shown in Fig. l, the mounting holes 12 and guide opening and locating flanges of the template are symmetricalso that the attachment can, by merely being reversed, function with the door and frame to form the hinge plate receiving recesses therein. This is true whether the door is hung for right or left-hand opening.

A novel means for locating the attachments on the door and frame is disclosed in Fig. 4 wherein an elongate stick 24 is provided with an abutment 25 at one end spaced from the end 26 of the stick a distance equal to the required top clearance of the door. Spaced from the end 26of the stick are marker means 27, herein illustrated as opposed points28, at required intervals depending upon the number of hinges to be applied. The gauge may be manufactured as standard equipment or can be made up on the job by a carpenter by taking a stick of wood long enough to cover the hinged section of the door and driving a nail in the end of the stick until the head projects beyond the end of the stick the required distance to form the abutment 25 for spacing the door and by driving through the stick nails to form the market means 27 at the prescribed intervals that it is desired to set the hinges.

In accordance with the present invention a novel method of setting the hinges on the door has been discovered. In carrying out this method the gauge is positioned adjacent the door with its top end 26 aligned with the top of the door, as shown in Fig. 6, and the gauge is then tapped or otherwise manipulated to cause the marker means 27 to apply suitable marking 29 to the door which is adapted to locate the router attachment. Then the gauge is positioned in the opening of the door frame with the abutment 25 engaging the top of the frame, as shown in Fig. 7, and the marker means tapped or otherwise manipulated to provide adequate marking on the frame for the location of the attachments necessary to provide the recesses for the hinge plates.

In the illustrated form of the invention only two hinge plates are being located. However, it is to be understood that any number of hinge plates may be supplied and it is merely necessary to provide the desired number of marker means 27 on the gauge.

After the door and door frame have been adequately marked, a plurality of attachments are then secured to the door and frame. This is accomplished, as illustrated in the exploded view of Fig. 3 showing an attachment being secured to the edge of a door, by having a hole 12 and a nail 13 aligned with the marking 29 so that the attachment is properly located lengthwise of the door. The depending flange or locating means will properly position the attachment with respect to the edge of the door. After the attachments are secured in place, a routing tool, not shown, is employed to cut out the recesses along the door and frame, thus enabling the hinges to be readily installed and the setting of the door to be accomplished quickly and accurately.

It will be apparent from the foregoing that I have developed a simple method of recessing the doors and frames for reception of hinge plates which greatly facilitates the hanging of the door.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
